more active compounds, where 14t that possesses a 4-octyloxy-phenyl-substituent was the most potent and displayed cytotoxic activity in the microM range. It is assumed that the oxazolinium salts act as alkylating agents, and undergo nucleophilic attack on the methylene adjacent to the ring oxygen where the oxazolinium ring parallels the aziridinium ring intermediate found in classical alkylating agents
取代的肉桂酰氯11被转化为(2-羟乙基)-恶唑啉鎓氯化物14,N,N-双-(2-氯乙基)酰胺16和(2-氯乙基)-恶唑啉鎓氯化物17。尽管衍生物14具有电子-供体取代基(Me或MeO)比被吸电子基团(NO(2),Cl或CF(3))取代的取代基更有效,细胞毒性肌动蛋白的差异不明显。一系列烷氧基取代的衍生物14中亲脂性的修饰导致活性更高的化合物,其中具有4-辛氧基-苯基取代基的14t在microM范围内最有效且显示出细胞毒活性。假定恶唑啉盐起烷基化剂的作用,
